标题：Öğrenci başarılarının belirlenmesi sınavından klasik test kuramı, tek ve çok boyutlu madde tepki kuramı modelleri ile kestirilen başarı puanlarının karşılaştırılması
摘要：The focus of this research is to test the estimation of achievement measurements in the test battery and to empirically compare the results after applying classical test theory, unidimensional and multidimensional item response theory models to Student Achievement Assessment Test (ÖBBS-2008) subtests of Turkish and Mathematics. It also tries to put forward the best model that estimates students’ achievement with less error as the comparison is being made. From the analysis of Turkish test's data results, it is identified that the ability parameters estimated obtained from the whole test under multidimensional IRT, have partially less error scores and reached more precise measurement than ability parameters estimated obtained from unidimensional IRT on the basis of sub dimensions and test scores obtained from CTT. Similar results were obtained in mathematics test results. Finally, it is found that parameters, obtained within the scope of multidimensional IRT, have partially less error scores.
